I did changed just the hostname on two last week with no issues. My IPs also remained the same, just a DNS update.

As we've added OSS, we've never explicitly placed the machine names in any configuration. Furthermore, no IP changes will be made, just the DNS name, so perhaps we are safe after all? bob On 12/13/2010 4:48 PM, Wojciech Turek wrote: I think that Andreas got confused and thought that you want rename OST. Renaming OSS is easy and don't require any Lustre reconfiguration if your Lustre configuration is based on IP addresses and not hostnames. If you have heartbeat, you need to change names in configuration Best regards, Wojciech On 13 December 2010 21:34, Bob Ball <[email protected]<mailto:[email protected]>> wrote: Yes, just the DNS name. From Andreas' response, it would seem this is not something I want to do. bob On 12/13/2010 4:11 PM, Lundgren, Andrew wrote: > Are you talking about renaming the DNS name of the host machine, or something > else? > > -----Original Message----- > From: > [email protected]<mailto:[email protected]> > > [mailto:[email protected]<mailto:[email protected]>] > On Behalf Of Bob Ball > Sent: Monday, December 13, 2010 1:49 PM > To: Lustre discussion > Subject: [Lustre-discuss] Renaming an OSS > > For administrative reasons, we want to rename an OSS.
